“…(8). Weighted average was used in order to prevent target classes with smaller instance counts from adversely affecting the results (Hempstalk & Frank, 2008). Friedman's rank test is a nonparametric test analogous to a standard one-way repeatedmeasures analysis of variance (Howell, 2013).…”

“…It has been successfully applied in many novelty detection and classification tasks, including communication network performance [3], wireless sensor networks [4], forensic science [5], detection of handwritten digits [6] and objet recognition [7], only to name a few. Moreover, it has been extended naturally to binary and multiclass classification tasks, by applying a single one-class classifier to each class and subsequently combining the decision rules [8].…”

“…The AUC is used in this work for comparisons because it is independent of any threshold used by the learning algorithm. It is not influenced by decision biases and prior probabilities, and it places the performance of diverse systems on a common, easily interpreted scale [14].…”

“…To compare classifier performance on the entire multi-class transactional dataset, we use the weighted average AUC, where each target class c i is weighted according to its prevalence [14]:…”
